Question

How do you find the perfect square (x+1)^2=0

Answer 1

By multiplying the term by itself (x+1)(x+1)

Some people like to use the box technique, which formats like this:

x + 1

x x^2 1x

+

1 1x 1

The terms multiply in columns, and then add all together

So

x^2 + 1x + 1x + 1 can be simplified to x^2+2x+1 = 0, which is the perfect square of (x+1)^2 = 0
